A mixture of 2-(2-chloroethoxy)-4-fluoro-1-nitro-benzene (91.3 g, 6 mmoles), 2-hydroxyethanol (0.57 g, 7.2 mmoles), and cesium carbonate (2.34 g, 7.2 mmoles) in DMF were stirred together at room temperature for 1 hour, diluted with water and extracted with EtOAc. The extracts were combined, washed sequentially with water and brine, dried over Na2SO4 and concentrated under vacuum to afford the title compound (0.63 g, 2.4 mmoles), identified by HNMR and mass spectral analyses.
